R52 Will not "see" a DVD

[johnpftd]

We recently bought a R52 and in an effort to clear the previous owner's data we used the restore program on the R52's hard drive to get back to factory defaults. The machine will see and give me access to any files on a CD, but it will no longer recognize any DVD I place in the drive. I have tried a cleaner disc with brushes on it but to no avail. Any ideas??

Sometimes deleting the ide drivers helps. Windows will install them again when rebooted.
